We had our usual walk by the canal today, and I did a bit more playing with monochrome when we returned. I took this photo of grass for the pattern and contrast, so it was a prime candidate for black and white:
The last part of our journey is by street, and this chimney pot caught my eye – an H in the sky:
I used The GIMP’s Chanel Mixer to change the image to monochrome, then added colour to turn it to something resembling sepia:
The H-shaped pot itself looks better in the sepia version, but I think the brickwork looks a bit unreal. Maybe it would have been better with only parts converted?
